Serial No. 403,730.

To all whom it may concern:

Be 1t known that I, Gnonor; II. HERR- Nnonnn., a cltizen of the United States, reslding at lzlornell, in the county of Steuben and Stato of New York, .have invented new and useful Improvements 1n Reflectors, of which the following 1s a specification.

This invention relates to reflectors particularly adapted for use in connection with locomotive furnace doors, and the object thereof is to provide in a manner as hereinafter set forth a reflector, whereby there is obtained the full lighting power of the furnace to assist the fireman while at work so that the ordinary firemans torch can be dispensed with.

A further object of the invention is to provide a reflector in a manner as hereinafter set forth which is -readily attachedto a locomotive furnace door, simple in construction, strong, durable, efficient in its use, and comparatively inexpensive to manufacture.

With the foregoing and other objects in View, the invention consists in the novel construction, combination and arrangements of parts hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto a pended.

In describing the invention in etail, refer.- ence is had to the accompanying drawings, wherein like reference characters denote correspondin parts throughout the several views, an in which Figure 1 is a front elevation of a locomotive furnace door showing the adaptation therewith of a reflector in accordance with this invention. Fig. 2 is a vertical sectional view of the door, also showing the reflector in longitudinal section. Fig. 3 is an inverted plan of the reflector, also showing the door in sectional lan. 4 is a perspective view of the bo y ortion of the reflector. Fig. 5 is a perspectlve view of the cut-ofi". Fig. 6 is a detail ofthe pivot for the cut off and the means for nialntainin the cut off from movement after it has een shifted toopen or to closed position.

Referring to the drawings in detail, 1 denotes a locomotive fire door which is hinged to a fire box as at 2. handle, and 4 a latch adapted to receive the free end of the handle for maintaining the door closed. i The foregoing elements are of 3 denotes the door.

known construction and are shown by way of exainple so that the adaptation of a rei lector in accord ance with this invention with a locomotive fire box door can be readily understood. The door 1, however, is provided with an opening 5 through which the light from the furnace escapes, the reflector being arranged in operative relation with respect to the opening so as to direct the light rays to enable the fireman to see to perform his duties at night without the use of the torch employed for such pur ose.

A reflector in accor ance with this invention comprises a semi-cylindrical body portion 6 having longitudinally extending in-. turned flanges 7 which constitute seats for a semi-cylindrical reflectin member 8 which is of a length to project s ightly ast the inner end of the body portion 6. 1e member 8 is prevented from longitudinal movement with respect to the body portion6 through the medium of a retaining screw 9, the latter extending through the body portion 6 and member 8, as clearly shown 1n Fig. 2.

The body portion 6 at its inner end terminates in a semi-cylindrical flan e 10 provided with openings 11 through which extend holdfast devices 12 for securing the body portion to the door 1. The flan e 10 surrounds the o ening 5 and is provi ed with a seat 13 w ich receives a semi-oval-shaped disk 14 whichconstitutes means for closin the opening 5, thereby cutting ofi the fight rays. The disk 14 and its lower end roject below the edge of said o ening aswelFas below the lower edge of the ody portion 6 and one side of said rejecting portion is formed with a lug 15 w iich extends at right angles with respect'to the disk. The lug 15 has formed integral therewith a circular disk 16 extending 1n parallelism with respect to the outer face of the door 1 and which has its inner face provided with a series of notches 17. Proj eetin outwardly from the lower portion of the diei 16 is a bevel-shaped extension 18 which is formed integral with an outwardly inclined handle 19, the latter at its inner end bein formed integral with the outer face of the disk 14 as at 20.

The fiange 10 at one end is provided with an opening 21 and further provided with a pair of vertically extending lu s 22 which are arranged in parallelism wit respect to each other and terminate at the edge of the opening 21. against the apertured end of t e Harige 10 The disk 16 is ada ted to abut and in closed position in Fi and the grooves 17 in the disk 16 are adapted to receive the lugs 22. The disk 16 is pivotally connected to the flange 10 through the medium of a headed bolt 23 which extends through the opening 21 formed in the disk 16, the head of the bolt being seated in a counter-sunk portion 25 formed in the inner face of the flange 10. The outer end of the bolt 23 is screw-threaded as at 26, the said screw-threaded end carrying a pair of nuts 27, 28. Surrounding the bolt 23 and interposed between the nut 28 and the outer face ofthe disk 16 is a coil compression spring 29, the function of which is to maintain the disk 16 in engagement with the flange 10 and furthermore maintain the lugs 22 in the grooves or notches 17. The tension of the spring 29 can be adjusted by manipulating the nuts 27 28. The spring 29 further constitutes a means for holding the cut-off l4'in a closed or open position as the case may be. The cut-off or disk 14 is shown in open position in Fig. l 2 and Fig. 3. T-he engagement of one of t e lugs 22 with one of thegrooves or notches 17 is clearly shown in Fig. 3.

When the disk 14 is moved to the position shown in Fig. 1, the light rays escape through the opening 5 and are reflected by the member, consequently enabling the fireman to see while performing his Work and Without necessitating the employment of the ordinary firemans torch. 'lhe lugs 22 in connection with the notches or grooves 17 provide means for controlling the light rays, that is to say the cut-off 14 can be adjusted to positions artially closing the opening 5 so that the voliime of light rays from the fur- .Ilace can be increased or diminished as is desired. If the light is too intense., by artly closing the cut-off the light can be iminished. The spring 29 will maintain the cutoff 14 in its adjusted position. l

By providing a reflector in accordance with this invention, it overcomes the dangerous practice of utilizing a burning torch while the engine is in motion,

as the glare being reflected from the glass of the front engine cab makes it impossible to detect danger signals ahead without looking out of the side cab Window which is very dan erous, especially in stormy weather.

T e reflector in accordance with this invention will also' enable one to dispense with the burning of the torch while the fireman is preparing his fuel and firing his engine without necessitating any expense, as the light rays are obtained from the fire box of the rnace.
